Performance. Although wear and field trials and actual storage of textiles are the ultimate in predicting the ability of treated fibers to withstand degradation, such studies are tedious and time-consuming. Accelerated performance tests have therefore been devised to relate fiber preservation to actual storage and exposure conditions. 

In Europe, a consortium of nine cities, backed by the EU, has conducted a large-scale field trial of fuel cell buses, together with an evaluation of pathways for the production, storage, distribution and dispensing of high-pressure... 

Development of optimum sizes for tanks and dikes comes through trial and error. Considerations include the availabiliw of real estate, the po.ssible use of standard-sized tanks for. smaller capacities, and the nature of potential foundation design problems caused by early tank-size seleaions. The de.signer should refer to API 12F for standardized shop-fabricated tank sizes. Larger field-fabricated storage tanks must be sized to suit each site. 

Formulation as Sprays. Virus formulations have usually been for application as sprays using conventional application equipment. Most viruses tested by researchers in field trials have been aqueous suspensions of filtrates or precipitates from macerated virus-killed cadavers. These are stable for long periods under refrigeration or when frozen and usually are easily tank-mixed with water and other adjuvants (12, 13). Performance of these simple formulations in field trials usually is equal or superior to more elaborate formulations. They are seldom practical for commercialization, however. Commercial formulations are concentrated precipitates because stable and concentrated product is needed for storage and shipping.

RAC samples from a processing study should be handled exactly as RAC samples from a field residue trial. They should be frozen as soon as possible following collection. Once the processing commodities have been created, they should be frozen and shipped to the analytical lab as quickly as possible. Both the RAC samples and processed samples from a processing study must remain frozen throughout the shipment and storage period of the study in order to preserve residue integrity. 

In the author s experience, field residue trials can be conducted in Latin America under complete compliance with all ERA guidelines and recommendations. More time does need to be spent in planning and preparation to ensure that the personnel involved in the testing have been trained in GLP and that this training, as well as the compliance of equipment, storage and archival sites, standard operating procedures (SOPs), and quality assurance (QA) audits, are properly documented. 

The hierarchical paper data file is organized in the same way the planned field residue trial example was developed. The protocol and final report are followed by test chemical information, test location information, application and harvest information, shipping and storage data, and analysis data. The analysis data is grouped by bench sheet to assist manual searches. 

The types and amounts of raw data generated In agrochemicals research were Illustrated by using a small planned field residue trial as an example. The large amount of raw data generated In this small example Indicates how throughly both the study and the archival storage must be planned. The diversity of materials to be archived also contributes to the complexity of the archival needs. 

The approach was quite simple. Trial and error tests were conducted in pilot plants, eventually leading to flie selection of a convenient surfactant or surfactant package that produced an emulsion sufficiently stable to withstand shearing and storage from the field to the refinery. The emulsions were prepared in situ, by means of down-hole emulsification. A nonionic surfactant was the obvious choice since the formation water could be quite salty (53, 54, 59).
